Patented May 17, 1921.,

Application filed June 12, 1920. Serial No. 388,815.

-hereinafter described and delinitely claimed.

In the accompanying drawings, hereby made a part hereof Figure 1 is a side elevation illustiatiiig an automobile wheel embodying my novel rim construction.

Fig, 2 is a side elevation of the rinri per 86 in its contracted state.

Fig. 8 is a section with the tire ornitted, said section being taken in the plane indicated by the line 8--8 of Fig. 1 and being 'of an enlarged scale.

Fig'. i is a fragmentary side elevation showing the 1neeting ends of the rim and also showing one of the rings on the rim.

Fig. 5 is a detail longitudinal section taken in the plane indicated by the line 5-5 of Fig. 6. V

Fig. B is a detail view Of the inner side of the rim showingthe means 'whereby the ends of the rim are looked in ablltting relation.

Vide the felly 1 of a wheel with threaded transverse bolts 2 and with wear plates 3, cach of said wear plates having on itsface a radially disposed rib 4. I also provide the felly 1 at its outermost corner with a bevel 5 that extends entirely around the iielly. Inassociation with the felly 1 I employ a metallic `felly band 6 having theouter angularly-disposed edge portion 7 and an inner angularly-disposed edge portion 8, said portion 8 being pro ected beyond the inner side of the felly as best shown in Fig.

trated.

8- Also in. association with the felly 1 I employ rim lugs 9 each of which is threaded on one bolt 2 and is provided in its working side with a groove 10- When each lug 0 is in working position as shown in Fig. 3 its groove 10 receives the rilo 1 on the wear plate 8 with the result thateasual turning movement of the lng 0 is precluded and yet when subjected to' stress the lng may be turnedon the bolt to a position at right angles to that shown in Fig. 8-

B'y oomparisonot Figi. 8 to -7 it will be noted that the i'm 1-1 is split at 12 and that one of the abuttiiig ends i s beveled as indicatedby 13, Fig. 4- lit will also be noted that extending throughout the length of the rim 11- at the inner side thereof are spaced and parallel ribs lt and 15; the rib 14s being rounded in cross section to ride to position on the edge portion 8 of the felly band 6', and the rib 15 being deeper than the rib 145 in about the proportion illustrated and be in g provided with a beveled surface 16 to conform to the edge portion 7 of the felly band 6-, At its outer side the rim 11 is provided with 'inner and outer marginal flanges 17 and 18 to engage rings 19 for retaining a tire 20 on the rim, and I would here have it understood that the flange 17 isproportionately deep. The practical advantage of this will be readily understood when it is stated that when the rim in contracted state is laid on .the flange 17, the said flange 17 will preclude disassociation of the rings 19 from the rini. Thus after being laid on the iiange 17 raising of the rim will be attended by raising of the rings 18 on the rim without liability of either of said rings 19 being disassociated from the riin. In addition to the features Inen tioned the rim 1s provided with an aperture .21 for the passage of a valve stem and is also provided at its inner side adjacent to its abutting ends with pairs of lugs numbered 22 and 23, respectively; the said pairs of lugs 22 and 28 being preferably, though notnecessarily, carriedby plates 2 1 and 25, riveted at 26 to the rim. I also provide the rim with a stucl 27 to enter a socket in the felly band 8 with a view to prevent" v ing ereeping of the rim on said band, .and when the plate 24s is employed I prefer that the stud 27 be carried by said plate .as illus- Pivoted at 28 between the lugs 22 and at 29 between the lng s 28 is a lever 30 for use in contracting the rim in expandby 31 in Fig. so that it may be readily grasped for manipulation. Manifestly the lever 230 when positioned as shown in 'Fig.

5 is in a dead center and therefore there is no, lability whatever of the ends of the rim casually moving out of their abutting relation. When, however, it is desired to contract the rim as appears in Fig. 2 the same may be accomplished by the expenditure of little eiiort in moving the lever 31 in the direction indicated by the arrow in Fig. 5. Again through the medium of the lever and by movement of the Same in reversed direction the ends of the rim may be expeditionsly and easily moved into their abuttingrelation when they will be' looked in such relation as beforedeseribed. The liig'S 23 are provided 21s best shown in Fig'S. 5 and 7 with studs 89 which are comple mentary to apertures 83 in the end portion of the rim b v which the bugs 29 are carried. In consequence of this when the lever 30 is moved into the position shown in Fig. 5 the studs B2 will enter the apertures and will thereby assist vervmaterially in the lockingor securingof the ends of the Tm in the abutting relation,

By particular reference to Fig'. 3 it will be observed that a'considerable space 3 1 is afforded between the felly band 6 and the rim 11. Phe said space Sd serves to accommoclate and to house the lever 80 and this without distortion whatever of the rim 11 or the felly band 6. In this connection it will be noticed that tight joints are formed loetweenthe rib l i and 15, on the one hand, and the angularly disposecl edge portions of the felly band, on the-other With the result that moisture and clustwill loe' eiiiectively prevented from gaining access to the lever 80. From this it follows that when the rim 11 is Slipped outwardly and Off the felly band 6, the lever 30 will always be found to be in a good worlzable condition.

By virtue of the ribs l and 15 on the rim 11 being disposecl at the edge portions 7 and 8 of the felly band 6, the said ribs 14 and 15 will, incidental to outward move- -ment of therim on the felly band, find on one lllg` and an aperture in the other end portion to receive said stud, of a lever pivotally connected with said lugrs.

The combination with 21. Split contractible and expansible rim having lus at the inner Sides of itsend portions and a -Stud on one ling and an aperture in the other end portion to receive said stud, of a lever pivotally .connected with Said lugsg` said lever beingcurved in conformity to the curvature of the rim and beingarranged to rest in a deadcenter when the ends of the rim are in abutting relation.
